What is the main purpose of repellants in pest control?

The main purpose of repellents in pest control is to repel pests using various methods. Repellents are specifically designed to create an unfavorable environment for pests, encouraging them to avoid certain areas or plants. This can be achieved through a variety of mechanisms, such as emitting odors or utilizing specific chemical compounds that insects find unpleasant or irritating. By using repellents, pest management strategies aim to prevent infestations without the need to kill the pests, making it a strategic option for those looking to manage pests while minimizing harm to beneficial organisms and the environment.

In contrast, the other options do not align with the fundamental purpose of repellents. Absorbing into plants relates more to herbicides or other types of pesticides that target specific pests. Attracting insects contradicts the function of repellents, as they are meant to deter rather than draw pests in. Lastly, controlling rodents refers to specific methods and products aimed at managing rodent populations, which is a different category of pest control entirely.
